[PATCH 0/3] nfsd: fix final setattr on delegated timestamps

[Jeff Layton <jlayton@kernel.org>]

Olga reported seeing a NFS4ERR_INVAL return on the final SETATTR before
a DELEGRETURN to set the timestamps. The first patch fixes that by
simply ensuring they are declared writeable. The second patch fixes a
related bug in the stateid handling in that same SETATTR. The last patch
adds a new tracepoint that I found useful for tracking this down.

It might be best to squash the first two patches into this one:

    f6b1cfab609d nfsd: handle delegated timestamps in SETATTR

The last one should probably go in on its own.

Thanks!
